shell指令碼實現自動生成awr報告

主要實現自動生成awr報告，程式碼思想非本人，但是有進行部分改造，之前網上的不能執行，經過部分改造可以正常執行的

生成語法

[oracle@hxy ~]$ bash ./dba_oracle_awr.sh -s HXY -f 20131125140000 -t 20131125150000 -p text -h /u01/app/oracle/product/10.2.1/db_1

指令碼如下

[oracle@hxy ~]$ cat dba_oracle_awr.sh
#!/usr/bin/bash
# ********************************
# * dba_oracle_awr.sh
# ********************************
# Usage: dba_oracle_awr.sh -s [instance_name]
#          -f [from time]
#          -t [to time]
#          -p [report type, html or text]
#          -h [oracle home]
#          -n [tns admin]
#
#         time format: 'yyyymmddhh24miss'.
#         E.g 201311251300 means 05:00:00pm, oct 04, 2013
